VALVE. y n

To all 'whom it 71mg/ cry/warn.' y

Be it known that JAMES lVAL'rnR Buooxs, a citizen or' the United States,residing at Baltimore, in the county of Baltimore City and State ofMaryland, has invented certain new and useful Improvements in Valves, ofwhich the following is a specication, reference being had to theaccompanying draw ings. y

llhis invention relates to valves and has for its object to provide avalve adapted for use in connection with a hose or like conduit andarranged to automatically shut off the supply of liquid.

Another object of the invention is to provide a valve having manuallyoperable means for opening the valve and automatic means for closing thevalve, said automatic means being controlled by the manually operablemeans when the valve is in its open position. p Another object of theinvention is` to pro- Vide a valve of this character including means foropening the valve and means for closing the valve, said means beingoperable independently of each other,

A still further object of the invention is to provide a valve of thischaracter wherein the` liquid passes through the valve stem and does notcome in contact with the operating parts of the valve.

A still turther object ot the invention is to provide a valve of thischaracter wherein the automatic closing` means cooperates with themanually operable meansto prevent ac cidental movement of the manuallyoperable means. y

lV ith the above and other objects in view, the invention consists inthe improved construction and arrangementy oi" pars to be hereinaftermore particularly described, fully claimed and illustrated in theacconi-- panying drawings` in which.

`lWigure 1 is a vertical elevation of the valve constructed inaccordance with an embodiment of the invention,

Figure 2 is a longitudinal sectional view showing the valve in its openposition,

Figure 3 ,is a section taken on the line :-Il of Figure 2,

Figure l is a detail view of one end of the valve casing showing thegroove of the set screw. f

reduced to provide a valve seat 7. rllhe ex.- terior portion of the end6 is threaded, to permit the valve to be connected tothe'pres `sureline, while the end S is also threaded, the purpose oit which will behereinafter described.

The exterior intermediate portion of the tubular member 5 is providedwith a heX- agonal collar 9 by means of which the valve casing may beapplied to the pressure line with the use of a wrench.

rlhe interior of the casing 5, irom the intermediate portion thereof tothe end 8 is enlarged to 4provide a shoulder 10 adapted to support awasher ll. Slidable within 'the asing 5 is a valve stem`12 having itsend 13 enlarged and threaded as at 14 for the reception o'l' thecoupling l5, by means of which the hose is attached to the valve stem.The coupling l5 is provided with a reduced portion 16 adapted to receivea hose or like conduit. Disposedin spaced relation to the threadedportion 14. of theenlargement 13 is a collar 17, adapted at times toengage the extremity of the end portion 8 to limit move ment of thevalve stem 12. The enlarged portion 13 is snugly mounted within theenlargement of the casing 5, while the valve stemv 12 projects through'the smaller passage oit the tubular casing to the end 6 thereof. Thevalve stem Yl2 `is hollow, to permit the passage of liqn idtherethrougl'l, the end portion 18 ot the stein being providedwith opposed outlet openings 19 which are closed/by means of the walls of thetubular valve casing.

rlheextremity 2O of the stem is closed and provided with an extension 2lwhich is threaded for the reception of a valve cap 22.

`The cap22 is provided with an annular `tlaingje 23 adapted to bedisposed. in aligny ment with the extremity of the end 6 of the casing 5and to surround the exterior portion nl the valve seat T. fl. washer 2lis carried by the valve cap and adapted to engage the valve seat 7 whenthe valve is in its closed position. The end portion 18 of the valvestem provided with a groove 25 which registers with the groove 26provided in. the 'inner surface of the end. 6 of the valve fcasinof.These grooves are intended to re- In order to permit t-he valve toautomatically close, a spring28 is disposed on the valve stein withinthe enlarged portion of the valve naming". Une endfotl `the spring` 'isadapted to engage the enlarged portion 13, while the other end of thespring isadapted to 'torce the Washer 1lfifn Vengageurei-it with theshoulder l() so as to preventl leakage of the valve.

An adjusting collar 29, is mounted on the end 8 ot' the casing,saideollar inelfud-ing a? 'handle B0 by means ot' which the Collar maybe rotated 4longgitiidinally of the casing.

rihis follarY hasoneend' portion* thereot extended inwardly to` providean lanniilai flange 31 which at times engages thecoiiafi" (tal'disengagement .of the collar troni the casing 5. rlivlie groove 32"isformed aecording` to the threads of the end 'S so thatlrotary movementoit `the eollafr 29 Will'perniit the collar to inlove 'longitiit'iinallyot the 'casing and Withiit the screw. The groove however, at theextremity oiY fthe end Spie eircula'r so t'h'at itfis i'inpossibletorthe screw to pass beyond the extremity of the end portion' S.

In use, the threaded end portion 6 of the valve casing` 5 iseonnected'to tlie'liressnre line,` and the hose or like4 `ronduitconnected to the coupling l5. It is ot course, obvious that the spring'28 constantly iirfi'esthe valve cap 22 to itsA closed position and isassisted in this operation through the pressureo' the liquid. Whenit isdesired' to discharge 'liquid from the hose, the handle nieinber '30 'isrotatedwa short distanceso as to forcef'the lflange linto engagementwith theend of the easingf as shown in Figure thereby opening the Valve.When thehan-dlqev-inenibei" 250y is lreturne'dfto its forni-er position7the yal'ye thenv acts automatically ffthrouggghP the medium of thespring to set olfthe supply poitionl, veoopeiates Withithe Vflange ii'tof prevent'accidental rotation the c llir 29.
